Fig. 5. — A detroquage table. 



To steady the tile while being handled, two guide 

 bars sloping from the edge of the bin-like table to the 

 lower edge of a central transverse partition are nailed on 

 in each worker's place, or four pairs in all. (See fig. 5.) 

 Each worker in a 7 hours day is expected to strip ?oo 

 tiles and also to wash the young oysters flaked from these 

 tiles. The oysters are then temporarily placed, still in 

 wooden trays fitted with wire netting bottoms, in the 

 storage tank which is an essential portion of the equipment 

 of a parker's working head-quarters ashore. 



As soon as time permits, the young oysters are taken 

 out, cleaned, and classed, with the aid of sieves having 

 meshes of 1 centimetre diameter, into two grades, those 

 measuring one centimetre and under, and those of superior 

 size. Oysters damaged in the process of detachment 

 are also picked out to be kept apart from their sound
